摘要/Abstract

摘要： 数据在传递过程中，经常出现两类现象:一些被传递的数据在传递中发生部分数据元丢失;一些未知的数据元入侵到被传递的数据内。这两类现象使得被传递的数据出现“异常”。利用一个新的数学模型，给出两类现象的理论研究与应用。这个新的数学模型是P集合(packet sets) , P-集合是由内P集合XF(internal packet set XF)与外P集合XF (outer packet set XF)构成的集合对;或者，(XF,XF)是P集合。给出数据的F依赖、F依赖的概念与特性，提出数据的依赖定理，给出异常数据被分离的应用。数据依赖是P集合诸多应用特性之一。P集合是研究动态数据系统的一个新理论与新方法。

关键词: P-集合，数据依赖，依赖度量，异常数据，数据分离，应用

Abstract: Two kinds of phenomenon often in data transference:some data elements are lost and some unknown data elements enter into original data. The data was changed into abnormal data due to such phenomena. By using a new mathematical model, theoretical research and application respect to two phenomena were given. This new model is called P-sets(packet sets). P-sets is a set pair which is composed by internal P-set XF(internal packet set XF) and outer P-set XF (outer packet set XF);or(XF，XF ) is called P-sets. In this paper, the concepts and characteristics of F-dependence and F-dependence were presented. I}he dependence theorem and the application of abnormal data separation were given. Data dependence is one of application characteristics and it is a new theory and method in dealing with dynamic data system.
